Document overseen by a lawyer
Letter of formal notice in Luxembourg
The firm drafts and sends your letter of formal notice: a firm, dated and legally grounded letter, often enough on its own to unlock an unpaid debt or a breach of obligation.
Legal content reviewed by Maître Cora Maglo, Avocate à la Cour, Liste I du Barreau de Luxembourg depuis 2009.
A formal notice is the step that precedes court proceedings. Coming from a lawyer, it lends weight to your claim and triggers certain legal effects, such as the running of interest and the engagement of liability.
Properly drafted, it resolves a significant share of disputes without litigation.
Your need
A debtor is not paying, or a partner is failing to perform its obligations.
Your own reminders have gone unanswered.
The risk
Without a formal notice, certain interest does not start to run and the evidence of your claim is weaker.
The longer you wait, the harder recovery becomes.
How we help
A firm formal notice drafted on the firm’s letterhead, setting a clear deadline and clear consequences.
Follow-up and escalation to proceedings where necessary.

FAQ
Frequently asked questions
Is a formal notice from a lawyer more effective?
Often, yes. It signals to the debtor your determination and the prospect of court proceedings, which unlocks many cases.
What happens if it goes unanswered?
The firm moves to the next stage: an order for payment, a writ of summons or another appropriate procedure.
Is a formal notice required before taking action?
Not always, but it is often useful and sometimes necessary to trigger certain effects, such as default interest and liability.

Testimonials
What our clients say
Had a consultation with Me Cora Maglo about my Luxembourg Blue Card application. She explained everything clearly: the process, timeline and documents I need, and helped me with my wife’s family reunification too. Honest and practical advice. I felt confident after talking to her.Farshid Pourlatifi
J’ai beaucoup apprécié le service de Maître Maglo : son sérieux, sa sympathie, son professionnalisme et sa disponibilité. Toujours répondu rapidement et clairement, avec des conseils pragmatiques, sans pousser à des procédures longues et coûteuses lorsqu’elles ne sont pas justifiées.Nathan Wirtzfeld
